For customers who require custom plating for proprietary and/or highly specialized applications, Olin Brass is an obvious choice. Within the company network and through close subcontractor relationships, we offer an unmatched range of value-added services, including electroplating, specialty slitting, surface treatments/coatings, and cut-to-length capability. Equally importantly is the emphasis we place on ease of doing business – you deal with only one contact and receive only one invoice on any given job, regardless of how many companies are involved in the work.

Every order is custom-tailored to the precise specifications of customer; hard drive reader head suspensions, photo etch components, deep drawn components, and solar panel substrates are just a few of the products that incorporate our stainless steels.

Premium Shape

The foundation of Olin Brass’ business lies in our East Alton, Illinois brass mill and the copper alloys that are produced there – up to a million pounds of finished coiled product per day.

Our portfolio includes rolled sheet and strip products made from some 60 distinct copper alloys, including high coppers, brasses, nickel silvers and other high performance copper alloys. In addition to standard gauges and configurations, we routinely work with individual customers to produce materials that meet their exact specifications.

Olin Brass manufactures many types of rolled and surface treated copper and copper alloy foils at its Somers Thin Strip facility, including specialty high-performance copper foils in a wide range of thicknesses and surface treatments. All are custom crafted to meet the precise individual requirements of domestic and international customers in the micro-electronics, energy, medical and other industries.
